Dark Matter May Be Remnant from Previous Universe, Scientists Suggest

Scientists have proposed a new theory suggesting that dark matter, one of the universe's greatest mysteries, could be a remnant left behind from a previous universe that existed before the Big Bang. This hypothesis offers a potential explanation for the elusive substance that makes up approximately 27% of the universe but cannot be directly observed. The theory could provide new insights into the nature of dark matter, which has puzzled physicists for decades as they attempt to understand its composition and role in cosmic structure formation.
